Health is the level of functional or metabolic efficiency of a living organism. In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental or social challenges. The World Health Organization (WHO) defined health in its broader sense in its 1948 constitution as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.”This definition has been subject to controversy, in particular as lacking operational value and because of the problem created by use of the word "complete" .Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction. Classification systems such as the WHO Family of International Classifications, including the International Classification of Functioning, Disability and Health (ICF) and the International Classification of Diseases (ICD), are commonly used to define and measure the components of health.

Identification of tuberculosis cases by port health screening in Essex 1997–2003

Abstract
Between 1997 and 2003 an annual average of 1867 new
entrants seen at the port of arrival were notified to the
communicable disease teams who now form the Essex
Health Protection Unit. We examined the number of individuals
who made contact with health services by linking
port health and tuberculosis databases with combinations
of surname, forename and date of birth the number of new
entrants developing tuberculosis. We also searched paper
records for all incidents of active tuberculosis in health
and residential care workers. Eighteen individuals were in
both port health and tuberculosis data sets; only one was
identified by new entrant screening. In the same period
there were 35 cases of active tuberculosis in health care
workers, only one of whom had been screened on arrival
in the United Kingdom, resulting in follow-up of 371 contacts.
The new entrant screening programme in Essex
should be stopped and resources diverted to improve followup
of new entrants, especially those who are health care
workers.

Background: Despite the known risk of tuberculosis (TB) to health care workers (HCWs), research suggests that many are not fully
adherent with local TB infection control policies. The objective of this exploratory study was to identify factors influencing HCWs’
adherence to policies for routine tuberculin skin tests (TSTs) and treatment of latent TB infection (LTBI).
Methods: Sixteen focus groups were conducted with clinical and nonclinical staff at 2 hospitals and 2 health departments.
Participants were segmented by adherence to TST or LTBI treatment policies. In-depth, qualitative analysis was conducted to
identify facilitators and barriers to adherence.
Results: Among all focus groups, common themes included the perception that the TSTwas mandatory, the belief that conducting
TSTs at the work site facilitated adherence, and a general misunderstanding about TB epidemiology and pathogenesis. Adherent
groups more commonly mentioned facilitators, such as the perception that periodic tuberculin skin testing was protective and the
employee health (EH) provision of support services. Barriers, such as the logistic difficulty in obtaining the TST, the perception that
LTBI treatment was harmful, and a distrust of EH, emerged consistently in nonadherent groups.
Conclusions: This information may be used to develop more effective interventions for promoting HCW adherence to TB
prevention policies. Informed efforts can be implemented in coordination with reevaluations of infection control and EH programs
that may be prompted by the publication of the revised TB infection control guidelines issued by the Centers for Disease Control
and Prevention in 2005. (Am J Infect Control 2004;32:456-61.)
